Same thing with whatever electronics that need to be installed. Build it on a panel in a shop and then just slap it on the wall at the installation site. I used to do this type of thing regularly on a small scale in previous jobs so I see no reason it can't be done on a residential home.

And I found someone who does it. Although he prefers pole mounts.
